The group in the long from of periodic table having three elements togther is

Options

A. zero group
B. `III^(rd)` group
C. `IV^(th)` group
D. `VIII^(th)` group

Answer

To determine the group in the long form of the periodic table that has three elements together, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Periodic Table**:
The periodic table is organized into groups (columns) and periods (rows). Each group contains elements with similar properties.

2. **Identify the Groups**:
The groups in the long form of the periodic table are numbered from 1 to 18. Some groups are known by specific names, such as the noble gases (Group 18), alkali metals (Group 1), etc.

3. **Examine Each Group for Element Count**:
- **Group 0 (Noble Gases)**: Contains elements like Helium, Neon, Argon, Krypton, Xenon, and Radon. This group has multiple elements but not exactly three together in each period.
- **Group 1 (Alkali Metals)**: Contains Lithium, Sodium, Potassium, etc. Again, not three together in each period.
- **Group 2 (Alkaline Earth Metals)**: Contains Beryllium, Magnesium, Calcium, etc. Similar to the previous groups.
- **Group 3 to Group 7**: These groups also do not contain three elements together in each period.
- **Group 8 (Transition Metals)**: This group is divided into three parts, and in each period, it contains three elements together.

4. **Conclusion**:
The group in the long form of the periodic table that has three elements together in each period is **Group 8**.

### Final Answer:
The group in the long form of the periodic table having three elements together is **Group 8**.
